Contingency Deco Plan

[Remy B.]

Ryan, 30+@7, I count, those are the common photography dives, not real dives, for what matters.

Not a bad critic, if you do count them, that is what work for you, nothing wrong with that, I just have a different criteria, I don't even look at my gauge nor my DC if that shallow and that short if I do happen to carry it, all the numbers are where they need to be, not real dives just relax entertainment, but that is me, not saying that I'm correct or is the correct thing to do.

Quite simply, the required deco is what's required to get out without being bent.

Some of the issues put forward in the thread can be equated to this analogy:

You're driving a car in the desert. It's 200 miles to the nearest gas station. You have gas to travel 100 miles. What speed should you drive at?

You need X deco to surface unhurt. If you complete X-? deco you're in trouble. Changing GF doesn't change that situation.

GF is set based on what you need to do. The OP hasn't got tech experience to know his GF needs, so it might seem very hypothetical to him. If the computer 'allows it', then he's safe. That's a recreational diving mindset... stemming from using computers in very forgiving no-stop scenarios.

No disrespect intended, but it's actually quite hard to have this sort of debate with divers who aren't trained or experienced at this level. There's so much more that needs to be grasped... and will be understood....as practical experience is gained in deco diving.

I'd suggest the OP makes a note to re-visit this thread once he's established a few hundred hours in deco experience. I'm entirely sure the concepts being explained would have a much higher clarity and logic at that time.

When it comes to technical diving, you need to learn to walk before you can learn to run.

Shipwreck penetration on trimix at 7ata is definitely a level that requires hundreds, if not thousands, of hours ability and experience development. There's underlying principles needed to grasp the subtleties necessary for understanding the theoreticals involved.

100% agree with you, as I enter in training and more experience I sure will look at it with different eyes.

For the moment I'm just asking, not executing nothing, I'm far from doing that dive.

Thanks

In which case you've had some good advice in this thread.

Recreational divers anticipating and researching technical diving often have very flawed assumptions about issues like reserves, redundancy and contingencies. Likewise, they won't appreciate the practical nuances with decompression planning and algorithm selection. They also fixate too much on the fundamental skills, loosing site of the fact that they are a mere prerequisite for tech....and not what technical diving is all about.

There's so much to technical diving that cannot possibly be grasped from only a theoretical perspective.
